PMC... are they that good?

To dismiss my post with no is arrogant. I tried to politely explain why older listeners might favour bright speakers, but you arrogantly dismissed my comments without thinking.

I’m not an expert, but unlike you I take into account research by experts. As one ages, ones hearing acuity degrades , and in particular one has lower sensitivity to higher frequencies.

Take a look at this graph:

https://www.thelancet.com/cms/10.1016/j.lanwpc.2021.100131/asset/ae98e797-96ca-49ee-9d7b-4eb92e8ceb0e/main.assets/gr1_lrg.jpg

It comes from this research paper in a medical journal:

https://www.thelancet.com/journals/lanwpc/article/PIIS2666-6065%2821%2900040-7/fulltext

The graph shows the average hearing sensitivity as a function of frequency for a range of ages. Note how the hearing sensitivity decreases significantly with age, and that the effect is greatest at higher frequencies. The vertical axis is in dB, a logarithmic scale. 3 dB equates to a doubling of sound pressure, and 10 dB to a subjective doubling of the sound volume. As early as the early fifties, average hearing declines by 10 dB at higher frequencies. In your early sixties, it can be down 30 dB, a huge amount. These are averages, someone with some hearing loss would be worse off, and about one third of people in their sixties have some hearing loss beyond the natural decline.

Hence my statement that I have a suspicion PMC are tuned to suit older listeners. In other words, it isn’t that older listeners prefer bright speakers, rather their hearing is such that for them bright speakers sound neutral. And as noted earlier, PMC are usually very expensive which puts them more in the range of older people with more wealth to their name.

I've not dismissed any of your posts, but as @Al ears said, no speaker company makes a product that age-related. You seem to be hung up on age and hearing. I know young people who suffer tinnitus or wax-filled lugs.

As I suggested in a previous post, go and demo a pair of PMCs. You'll then be better qualified to comment.

Precisely, however I very much doubt any manufacturer voices their speakers for a certain age group.
They either fit into your listening room or they don't, simple as...
if expensive speakers are designed for those that can afford them then I wonder when Magico speakers will become available to me....

Unless you have inside information. and I don’t, the truth is we don’t know how PMC voice their speakers. My guess is that the hippy owner decides on the house sound for non professional speakers, but that’s just a guess.

But whether or not they deliberately voice them for older listeners - and of course you might be right that they don’t - the bright characteristic of the ones I’ve heard probably appeals to older listeners for the reasons I gave.

The person who bought my PMCs commented that they sounded bright when he first heard them. Here’s a review of the Prodigy 5 also showing a bright presentation.

Note that I’m not giving a value judgement, people should simply buy what they enjoy, and tell anyone that disagrees where to go. Personally I prefer bright to the opposite.

No Al Ears expressed his opinion, just as I expressed mine.

Since you’ve stated what you claim to be a fact, I’d be really interested to see the proof. It’s always good to learn something new.

My opinion is based on owning a pair, that's the only fact I know about PMCs. Instead of bleating like a child, go and listen to some PMCs. Only then will you agree or disagree with my opinion.

You have no interest in demoing a pair, you're more than happy to tap away, criticising others, like most keyboard warriors.

Joys of the internet.

My previous pmc twenty 21's were highly detailed and a bit on the lean side of neutral....definitely not bright sounding......it's the first thing I noticed when I got the Neat petite classics home......I still miss that timbre of transmission line bass and glorious detail.....I also like the Neats....is it wrong to like lots of other stuff?

Having had the Neat Petite Classic at home to compare with my 21s, I couldn't agree more with that assessment.
To me the PMC is not bright - but compared to some other speakers and especially to listeners with a dislike of open, clear treble, it could easily be described as bright.

All frequencies and all detail need to be properly heard.
A wrong sounding speaker is one that makes an open triangle sound as if it's being grasped between two fingers when struck, some speakers really are that bad.....muted treble - instant no, thank you very much - good only for background music for the 'pipe and slippers' brigade (misguided old and young alike).

That seas tweeter is/was very very good indeed.....in fact I actually traded in the pmc's for the Neat petite classics.....the pmc's were in excellent condition....the guy's at the shop must have had a good listen to them......I got a txt message from the seller at the shop actually telling me how impressed he was with them......a few months later, said shop were /are selling pmc speakers.

There’s no need to be offensive.

I have said many times in this thread that I owned some PMCs. I’ve demoed numerous examples too.

you're more than happy to tap away, criticising others, like most keyboard warriors.

And yet the person criticising others is you.

And yet objective messurements prove that PMC speakers - or at least those measured - are bright.

This sums up the whole problem with most hifi reviews. The author writes some lovely prose extolling the virtues, or otherwise, of the speakers under test, but presents no measurements. Thus the reader is solely dependent on one person’s tastes, and auditory physiology.

Something I do like about Richer Sounds and Sevenoaks is that the staff just tell you to demo the product. I’ve been in shops that gave me sales patter, clearly favouring the more expensive models.

The Sea's tweeter I recall buying a pair of those for my DIY two-way cross over speakers. I was using duck dun and feathers stuffed inside polyester pillows for the damping. The extraction of detail from Seas were really good.

Its hifi guys take it easy.

The biggest problem I have with PMC is the transmission Line itself. Its doesn't work in all rooms and when does it does work if feels a bit lack lustre in my opinion, especially when compared to brands such as Revel (m106) which have an exciting and much stronger presentation. (Which I might add are almost ruler flat with only small bumps. People really shouldn't sit on this brand and give them a listen.)

Though good the sea's tweeter in these comes across even brighter than it otherwise would as the mids I feel are almost none existent and this is the danger of looking at charts.

I was really disappointed with the 20/23's when I had them for extended loan.

Without a doubt one of the worst speakers Ive had in my room along with ATC SMC 19's the reviews just did tally up with my experience at all. And I didnt measurements to tell me so. Ive listened in many rooms around the house and it other houses and there just lack lustre.

Newer PMC's I couldn;t pass comment

Just my opinion
